CORPORATION OF GEORGIA.

THREsHrNG-Mi-icnmn.

To all whom it may concern I Be it known that 1, JOHN L. HARRINGTON, a citizen of the United States, residing at l l instonSalem,'in the county of Forsyth and State of North Carolina, have invented certain new and useful Improvements in Threshing-Machines, of which the following 1912, and it is an object ofthe invention to provide a novel and improved machine of this general character which can be em-. ployed with equal "facility in the picking or separating of peanuts v and in threshing wheat or other grain.

lcsscarrier for the vines or straw, and with Anotl er object of the invention is to provide a novel and improved machine of this general character wherein the separated peanuts or grain are effectively freed of foreign matter, such as dirt, vines, straw and the like, andwvherein the machine operates in a manner to substantiallyeliminate loss in the desired product. l

An additional object of the invention is to provide a novel and improved machine oi": this general character. wherein the peanut vines are first delivered to a'coacting cylinder and concave, and whereln the working face of. the COHCEEYE'lS smooth and unobstructed, and \vhicl'iconcave is mounted inworking position in such a manner as to permit its ready replacement by a tooth concave, so that the machine may be readily employed in connection with wheat or'other 'r'un.

b L p i i i I 5 Furthermore it 15 an ObJQCiT o1 the. invention to provide a novel and improved machine or this general character including an endless carrier for the vines or straw, and

upon which the concave discharges, and where n a vibratory screen or separating element positioned below and in close proximity to the upper or. receiving stretch of the carrier."

A still'turther object of the invention is to provide a novel and improved machine of this general character embodying an end- Specification of Letters Patent. Patented A110; 24 1920 Ap'plication filed November 3, 1919'. Serial assesses. i

which coacts a picking mechanism which operates to separate peanuts carried by the vines when traveling with the carrier, and which mechanism also operates to facilitate the separation of grain which may be car ried by the straw.

The invention also has for an object to provide a novel and improved machine of this general character including a carrier and a picking mechanism coacting therewith, and wherein said picking mechanism includes means adjustable with respect to the carrier to impose pressure upon the vines or the like, moving with the carrier to'fa cilitate the operation of the machine.

The invention has for a still further object the provision of a novel and improved machine of this general character embody ing a separating element delivering upon members for conveying the sep rated peanuts or grain to a point substantially central of the screening element, and delivering the matter carried thereby to a riddle positioned therebeneatlr to effects further means for separation, and wherein an air blast coacts withsaid riddle to carry oil dust or other relatively minute particles of waste.

It is also an object of the'invention to provide a novel and improved apparatus or this general character embodying means whereby the tailings, and particularly the tailings separated by the riddle are returned tor further treatment by the chine so that the waste of the product separated, such as peanuts or grain, is substan tially entirely" eliminated.

The invention consists inthe details of construction and in the combination and arrangement of the several parts of my improved threshing machine whereby certain important advantages are attained and the device rendered simpler, less expensive and 7 describe the same with reference to the accompanying drawings Figure 1 is a view in side elevation with thereto Fig. 6 is a fragmentary sectional view taken substantlally on the line of Fig.5; i

Fig. 7. is an enlarged fragmentary view "in cross section illustrating a mounting for the vibratory screening element or sieve, as herein included, and the parts ad acent thereto;

Fig. 8 is a sectional view taken through a supplemental "riddle or sieve, which is employed when the machine is used in connection with wheat or other grain, and,

Fig. 9 is anelevational view detached, of.

the memberherein employed for maintain- 'ing the discharge nozzle of the fan casing in desired position, or adjustment with respectto the riddle.

As disclosed in the accompanying drawings, F denotes a portable frame constructed in accordance with the requirements of practice, and which is provided at one end with a feed trough 1, which delivers upon a con cave C. The concave C is particularly illustrated in Fig. 2 of the accompanying drawing, and which figure illustrates the machine in assembly for use in connect on with peanuts. It is to be particularly noted that the concave C is lmperi'orate, and has its working face'i 'ree andunobstructed. The concave C is adapted to be readily removed, so that the same may be replaced with a tooth concave of a conventional type when it is desired to employ the machine in connection with wheat or other grain. The concave C is supported, as indicated at 2, for swinging movement in a vertical direction toward or from the coacting tooth cylinder T, L116 occasions of practlce may require, and as disclosed in Fig. 2 the vertical swinging adjustment of the concave C is accomplished through the instrumentality of a cam 23, coacting with a shoulder 4, carried by the concave. As this particular means for adjusting the concave C forms no part of my present invention, it is believed that adetailed description and illustration is unnecessary.

The peanuts and the vines, as lifted from the ground, are thrown in a conven- I well known manner by the cylinder ill. The

cylinder T, as is well known,'serv'es to carry the peanuts andvines over the concave; The concave delivers upon an endless carrier E, and-more particularly the upper stretch thereof. The upper stretch of the carrier E extends from a point in advance ofithe, c011- cave to a poi t immediately adjacent the rear end of'the frafnef The carrier E comprises the side chains 3, passing around the ,sprocket'wlieelsetf fixed to the suitably positioned shafts 5, r0} tatably supported] by and. extendingjtransversely of the frame F. Each of the'ch'ains 8 coact with theidle guide wheels orpulleys 6, whereby saidchains are prevented from sagging. One of the shafts 5 has each end portion engaged with an adjustable bearing 7, whereby the chains 3" may beheld nndei" proper tension. The opposite shaft 5e:- tends to a sidefof the franie'F and'said extended portion has affixed theretoa sprocket wheel 8, having in drivingconnection therewith the chain 9. Thechains 3. are connected by the equidistantly spaced transverse members 10, each provided with aseries' of upstanding fingers ll of desired length.

The vines or the like, 'as delivered upon the carrier are carried rearwardly of the frame F and theseparated peanuts pass through the vibratory screening felement or sieve S positionedto and in close proximity to the upper stretch of a carrier EX The c eening element or sieve S is ofa length'to I substantially bridge the space between the shafts 5, and is of a width substantially equal to the space between the side chains 3.

The screening element or sieve S 06111- prises the elongated side members 12, having secured tothe upper edges thereof in any desired manner, the reticulated'fabric or screening 14, the openings of which being of a size to readily permit the passagetherethrough of the separated peanuts.

At predetermined points longitudinally thereof the side members 12 are connected by the cross members 15, which have their opposite ex remities disposed through the longitudinally directed slots 16, formed in the side walls ofthe frame F, whereby the element or. sieve S is supported. in applied position and capable ofen'dwise vibratory movement or reciprocation.

Each'end por ion of across member 15, and preferably the central member has engaged therewith the upper end portion of a vertically disposed hanger l7 pivotally sup ported intermediate its length, as at 18, by the acent portion of theframe F. Upon rocking or swingin'g moveme'nt being imparted'to the hangers 17, the desiredvibrat1on or reciprocation of the element or sieve S is effected to facilitate the desired func tioning of such element or sieves.

The separated peanuts, together with foreign matter passing through the element or sieve S, drop upon the upper stretches of the longitudinally alined endless aprons or drapers 19; The adjacent portions of the aprons or drapers 19 are spaced apart, as

at 20, to afford a discharge passage and the upper stretches of the aprons or drapers 19 move in a direction toward such passage or opening, so that the material carried by the aprons or drapers will be discharged through said passage or opening 20.

Each of the drapers 19 passes around the drums'2l, carried by the suitably positioned shafts 22, rotatively supported by the frame F. 'Each end portion of the outer shaft 22 is mounted in an adjacent bearing 23, Whereby said apron or draper may be maintained under desired tension.

Adjacent shanks" 22 extend beyond the side of the frame F, and have afiixed thereto the sprocket wheels 24, with which is operatively engaged a driving chain 25 in driven connection with the drive shaft26, suitably supported bythe' frame F. The chain 9, hereinbefore referred to, is also in driven connection with the shaft 26, as illustrated in Fig. 1 of the accompanying drawings.

It is to be noted that the chain25 coactswith the sprockets 24 in a manner to cause the upper stretches of the aprons ,or drapers 19 to travel in a direction one toward the other,

or in a direction toward the passage or opening 20, hereinbefore referred to.

The hangers 17, together with the hangers 17 have their lower extremities operatively engaged with the side plates 27, supporting a riddle 28. The openings of the riddle 28, are of a size to permit the passage therethrough V of the separated peanuts. The

' hangers 17 and 17 support the riddle 28 for vibratory movement, and said riddle 28 is' lower end portion of "the housing or casing 30 for an elevating mechanism. The upper end. ortion of the housing 1 or casing-30 discharges within the trough 1, so that the tailings can be caused to be again treated by the machine, wherebythe loss of peanuts or the like is substantially eliminated. The elevating mechanism within the casing or housing 30is of a conventional type, and for whlchreason a detailed V description and illustration is believed to be unnecessary other than to say that such mechanism is in driven connection through the medium of the chain 31, with a sprocket 32, fixedto one of the inner shafts 22.

The peanuts passing through the riddle 28 are received on a forwardly and downwardly inclined table 33, suitably supported by the frame structure, and underlying said riddle. The table 33 is provided with a series of transversely spaced slots 34, through which extend from below the revolving saws 35 As is particularly illustrated in Fig; 2, two longitudinallyalined saws 35 extend through a slot34, and for which reason said saws are arranged in two transversely dis posed series. The saws 35 of each series are suitably affixed to a transversely disposed shaft 36, suitably supported for rotation by the frame F, and in a manner whereby said shaft 36 and the saws carried thereby may bereadily removed from work ing position.

[The adjacent ends of the shafts 36 are operatively connected, as indicated at 37, for unitary rotation, and one of said shafts 36' is in-- driven connection with a shaft 22 by a chain 38, indicated by dotted lines in Fig. 2.

The saws 35 engage the peanuts delivered upon the table 33; and operate to stem said nuts, and otherwise clean the same. The

cleaned nuts are discharged fromthe table 33 into the delivery spout or trough 39 extending transversely of the frame-0n a predetermined downward incline, and delivering at one side thereof.

The desired vibration or oscillation of the riddle '28 is obtained through the medium of the pitman 40, operatively engaged at one end portion, with the lower extremity of the hanger 17, and the opposite end portion of the pitman 40 is operatively engaged with a shaft 41, suitably supported by the frame F; Theshaft 41 has afiixed thereto a pulley 42, around which passes a driving belt 43. The belt 43 is'also disposed around a pulley 44, fixed to the shaft 26, whereby said shaft 26 is properly driven. The belt 43 isadapt i if ed to be engaged with a suitable source of power, and preferably with the driving pulley of'a tractor, although I donot wish to be understood as limiting myself in this respect, as it is tobe understood that the shafts 41 and 26 may be rotated iirany manner which best meetsthe requirements of practice. Overlyingthe rear end portion of the upper stretch of the'endless carrier E and extending along 'the major length j thereof, is a picker frameP, including the 7 12b.

longitudinally spaced cross bars 45. De-

pending from the bars 45 are the picker: teeth 46, of a type substantially the same as disclosed in my prior Patent" No.

1,035,437, hereinbefore referred to. The teeth 46 are yielda ble and passing between adjacent teeth 4 6 are the upstanding fingers 11, he-reinbefore referred to, and which'is particularlyillustrated in Fig.6 of the accompanyin drawings. As the upper stretch ofthe carrier E travels rearwardly and under the teeth ac, sai'djteetlroperat'e to pull or pick the peanuts from the vines or Hahn, and substantially all of the pea nuts thus picked'fi'om the vines drop upon and through the element or sieye. S. 1

The. halm is discharged by the carrier E at the rear end of the frame F. or machine,

and falls clear-thereof,

In order to. prevent thevines or ,halm passing under the teeth 46,. from becoming clogged within said teeth, and thereby interfering with the, requisite operation of the machine, I find it of extreme importance to provide means for maintaining a. downward pressure upon the vines or halm.

As herein disclosed I arrange below the picking frame P a plurality of transversely spaced and connected pressure bars 47, each said bars extending betw en longitudinally alined adjacent teeth 46. The bars l7 are adjustably engaged with the frame P, or more particularlythe cross bars 45, thereof, by the upstanding threaded shanks 48, extending through certain ofsaid cross bars. Engaged with each ofthe shanks as above and below the co'acting bar' 45. are the clamping or holdmg members or nuts 49, whereby the bars 4:7 may be maintained in desired positionwith respect to the upper stretch of the carrier E. The'frame P, hereinbefore referred to, is mounted in workingposition in substantially thefsame manner as. disclosed in my prior patent, hereinbefore referred to, and for which reason a detailed description of such mounting is not believed necessary. I

50 denotes a fan casing loosely mounted upon the transversely disposed shaft 51, rotatably supported by the frame F, and

said casing 50 ispiovided with a discharge spout or nozzle 52 for delivering an air blast or current rearwardly of the frame, and which blast or current operates in the well known manner to carry off. dust or other light particles of waste or trash, which is received upon or passes through the;

riddle 28. r v Y The shaft 51 has fixed'thereto and within the casing 50, the fan blades 53 of a conventional type, and said shaft 53 is in driven connection through the medium of the belt 54, with a pulley 5 5, fixed to oneof the shafts bereadilyraisedor lowered to direct the air blast or current, as best meets the' requ ra having the casing 50 loosely mounted upon the shaft 51 the nozzle or spout 52 may ments of practice. The casing 50, or more is maintained in desired position by a cross beam or member 56, having its opposite end portions suitablyengaged with the frame F, and preferably through the instrumentality of a belt '57 passing througha transversely directed slot 58, in each end portion of the member The slot 58 permits the'mem} ber5Q to' be vertically adjusted in accordance with the adjustment of the nozzle or spout 52. The opposite end portion of the member is preferably provided. with the hand grasp 59,,to' facilitate the manipulation thereof. f
